The selection of competent election committee members is a critical aspect in ensuring the success of a fair and transparent election process. However, the subjective nature of this selection process necessitates a data-driven approach to optimize the selection of officials who meet the required competency criteria. This research aims to classify the competencies of prospective election committee members using the Decision Tree algorithm based on demographic data and technological attributes of the population. The study employs the Knowledge Discovery in Databases (KDD) methodology, which includes the stages of data selection, preprocessing, transformation, data mining, and evaluation. In this process, data collected through various attributes are processed to build a classification model. The Decision Tree algorithm is applied to extract patterns from the data, resulting in a decision tree that can classify individuals into different competency classes based on existing features. The research findings indicate that the Decision Tree algorithm effectively classifies respondents into several competency classes that represent varying levels of skills and interest in the election process. The model shows that Class 4 is the dominant class, indicating that most respondents have moderate competency in technological skills and interest in elections. Class 3 represents individuals with higher technological skills but moderate interest, while Classes 2 and 1 represent individuals with varying combinations of interest and skills. This study demonstrates that using the Decision Tree algorithm in the KDD process is highly effective in objectively classifying the competencies of prospective election committee members. By analyzing the interactions among relevant attributes, the model provides insights that can improve the accuracy of election official selection. This data-driven approach can be adapted to other contexts requiring competency classification, offering broader benefits for various criteria-based selection systems.

The development of information technology significantly benefits various activities, particularly for students, by facilitating access to information and supporting academic tasks. However, students majoring in Information Technology often face challenges in selecting a suitable laptop due to the wide range of options with varying specifications and prices. This study aims to develop a Decision Support System (DSS) based on the Simple Additive Weighting (SAW) method to assist in choosing the best laptop. The SAW method was selected for its ability to evaluate multiple criteria through a weighting process. The study utilizes five main criteria: price, processor, RAM, storage type, and storage capacity. Data were collected through interviews and observations at the "IComp" laptop store. The analysis process involves matrix normalization and preference value calculation to determine recommendations. The DSS recommends the best laptop based on the highest preference score: Lenovo IP Flex 5 (0.78), followed by Lenovo IP3 (0.77) and HP Pav14 (0.76). The results indicate that these laptops offer an optimal balance between performance and price. The web-based sy stem designed accelerates the evaluation process, enhances objectivity, and improves user accessibility. The implementation of the SAW method proves effective and accurate in determining the best laptop, particularly in scenarios combining cost and benefit criteria. The system successfully meets the needs of Information Technology students by providing relevant and reliable results. This study successfully develops a DSS using the SAW method for selecting the best laptop. The system designed is effective and reliable for multi-criteria decision-making. Future research can integrate real-time data and broader user surveys to improve result generalization, making it applicable to other product selection contexts.

Sampah adalah hal yang sangat krusial yang menjadi masalah tersendiri jika tidak terkelola dengan baik, dengan dampak yang dapat memberi pengaruh pada berbagai sisi kehidupan karena berkaitan dengan kebiasaan atau kultur masyarakat. Sehingga sampah dianggap penting untuk dilakukan pengelolaan dengan baik dan benar. (Wahdatunnisa, 20016). Dalam masyarakat dengan kepekaan terhadap lingkungan yang masih rendah, timbulnya sampah selalu memberi permasalahan yang dianggap begitu rumit. Terlihat banyaknya kondisi yang kurang menyenangkan baik dari segi baunya yang tidak sedap ataupun estetikanya, kondisi demikian dapat juga mengundang berbagai lalat yang dapat hinggap pada timbunan sampah tersebut. Dalam keadaan demikian dapat berdampak pula pada menurunnya kualitas lingkungan yang juga secara tidak langsung dapat memberi permasalahan yang besar, apabila tidak tertangani dengan baik. Termasuk terganggunya Infrastruktur kota, menurunnya kualitas kesehatan masyarakat ataupun lingkungsn hidup (Purwaningsih, 2015). Sampah di laut akan memengaruhi atau menghambat proses tumbuhnya terumbu karang, sehingga cahaya yang datang yang menjadi sumber utama bagi pertumbuhan karang tidak akan mampu menembus kedalam dasar laut karena adanya sampah yang menutupi karang . Terjadinya dampak yang tidak langsung pada ekologi laut akan memberi pengaruh pada habitat biota laut yang semakin berkurang bahkan perlahan akan mengalami kepunahan. Jika kita akan membandingkan dengan ekonomi terkhusus pada pariwisata,maka sampah justru memberikan dampak yang lebih besar. Adapun dampak yang lebih besar tentunya tetuju pada manusianya yang terkena langsung dampak karena dapat mengurangi keuntungan-keuntungan dari segi ekonomi. Kurangnya daya tarik oleh para wisatawan untuk melancong kedaerah tersebut disebabkan pemandangan sampah disepanjang pantai yang terlihat kurang baik. Seperti halnya sampah-sampah tersebut boleh saja menempel pada tubuh organisme laut seperti ikan, sehingga akan berdampak pada menurunnya kualitas ikan sehingga nilai jualnya akan menurun pula yang akan merugikan para nelayan setempat. Sampah yang berada di pantai akan sangat memberi pengaruh pada kesehatan manusia jika mengalami kontak langsung misalnya : benda tajam, pecahan kaca,logam yang sudah berkarat dan benda-benda tajam lainnya yang memungkinkan berada di daerah pantai ataupun didasar laut

Latar belakang: Penerapan perilaku hidup bersih dan sehat di masyarakat masih rendah karena kurangnya sosialisasi terkait manfaat dan risiko bila tidak menerapkan perilaku hidup bersih dan sehat dalam kehidupan sehari- hari. Karena rendahnya sosialisai perilaku hidup bersih dan sehat maka kemauan masyarakat dalam penerapan juga rendah yang berakibat kepada kesehatan masyarakat yang terganggu. PHBS adalah upaya untuk memberikan pengalaman belajar bagi perorangan, keluarga, kelompok dan masyarakat dengan membuka jalur komunikasi, memberikan informasi dan melakukan edukasi untuk meningkatkan pengetahuan, sikap, dan perilaku, melalui pendekatan pimpinan (advocacy), bina suasana (social support), dan pemberdayaan masyarakat (empowerment) sehingga dapat menerapkan cara-cara hidup sehat, dalam rangka menjaga, memelihara, dan meningkatkan kesehatan masyarakat (Depkes RI, 2011). Pengabdian kepada masyarakat dalam bentuk penyuluhan bertujuan untuk meningkatkan pengetahuan masyarakat terhadap bagaimana meningkatkan kesadaran individu-individu dalam menjalani perilaku kehidupan sehari-hari yang bersih dan sehat pada anak-anak di dusun Mekar rejo desa Banatorejo. Metode kegiatannya dimulai dari survei tempat penyuluhan , membuat materi penyuluhan dan pelaksanaan penyuluhan.

Penambahan jumlah udara pada proses pembakaran diyakini akan dapat meningkatkan performance dari suatu mesin. Salah satunya dengan mengurangi jumlah sekat pada filter udara. Udara yang masuk ke ruang bakar terlebih dahulu akan di saring melalui filter udara agar selalu terjaga kebersihannya. Hal ini tentu saja merupakan suatu hambatan yang menghalangi udara yang akan masuk kedalam ruang bakar. Dengan pengurangan sekat pada filter udara tersebut maka hambatan yang ada akan semakin berkurang dan udara yang ada untuk proses pembakaran akan terpenuhi sehingga akan terjadi pembakaran yang sempurna. Dengan demikian penelitian bertujuan untuk mengetahui pengaruh jumlah sekat filter udara sebagai  upaya meningkatkan performance mesin diesel. Penelitian ini menggunakan metode eksperimen yang menguji jumlah 153 sekat, 144 sekat dan 135 sekat. Dari setiap jumlah sekat dilakukan pengujian menggunakan variasi putaran mesin. Pada jumlah sekat filter udara 153 sekat konsumsi bahan bakar lebih hemat,dan efisiensi juga lebih tinggi. Pada jumlah sekat filter udara 144 sekat, konsumsi bahan bakar,putaran output mesin dan daya engine akan meningkat pula. Pada jumlah sekat filter udara 135 sekat, konsumsi bahan bakar akan menjadi lebih boros tetapi putaran output dan daya engine juga meningkat dengan efisiensi lebih rendah.  Kata kunci : Filter udara, performance dan sekat.
